5headers = {"Authorization": f"Bearer {api_key}"}
6
7response = requests.post(url, headers=headers, json={"name": "My Conference"})
8
9if response.status_code == 201:
10    print("Conference created successfully!")
11    print(response.json())
12else:
13    print("Error creating conference:", response.status_code, response.text)
